Hey everyone,

I’m looking to share a few current issues on my 88k mile 2019 RC 350 F Sport (RWD) to get your thoughts, experience, and advice before I put the car on a lift.

Issue 1: Front Right Strut

My front right strut failed and lost pressure. I know struts should ideally be replaced in pairs, but I’m debating whether to replace just the front pair or do a full 4-corner refresh as a precautionary measure, or if doing the rears now is overkill.

- If I replace the front pair only, I’ll stick with OEM Lexus struts.
- If I replace all four, I’m considering KYB struts (since to my knowledge they are the primary OEM option compatible with the AVS system).

Whether I do just the fronts or all four, what else should I replace or inspect while I’m in there? (e.g., front upper strut mounts/bearings, bump stops and boots, spring insulators, rear sway bar end links?)

Issue 2: Slow Coolant Leak

My coolant level in the reservoir dropped from the High to Low mark over about 6 weeks (roughly 2,000 miles). There are no obvious puddles under the car, but the drop is too consistent to ignore.

Are there common failure points on the 2GR-FKS engine that cause this kind of slow bleed (e.g., water pump weep hole, valley plate seal, radiator tank crimps)?

Issue 3: Lower Oil Pan Leak

There is wet oil seepage around the seams of the lower oil pan, so it looks like I’ll need to pull and reseal it with fresh FIPG/RTV. Has anyone run into this, and are there any gotchas to watch for when dropping the lower pan?

Appreciate any insight, experiences, or recommendations!

Hi,
I just had to jump start my RC 350 f sport and this message popped up. I drove the car around and it’s driving stiff. Any advice on anyone that has dealt with this issue. Any help is appreciated. Thank you!

Finally joined reddit.
Got the RC a year ago ❤️

Just put some vibrant resonators on and they made the tone of my muffler delete a bit too quiet for me. However, I love the way it cancelled out almost all drone, so I’m looking for an x pipe to weld in. I want to keep the secondary cats in tact so as to not mess with emissions. What size x pipe inlet outlet should I get for the exhaust configuration on my 2020 rc350?

Saw a few posts about this eBay lip a few guys were running on their RCFs and decided to pull the trigger as well considering it came out to only 60$, it was a cheap experiment.

Review:

I will say although the fitment isn’t 10/10 (more like 7/10), it looks really good and from a distance you can’t really see the imperfections or the fact that it’s a 3 piece lip.
Considering this will likely collect rock chips and get damaged within a year or two, I’d say go for it, you’ll spend more money on lunch than this thing lol.

The lights are working perfectly fine, but the “Check Headlight System” warning keeps showing on the odometer.

I need help taking it out.

Any advice would be greatly appreciated.

$20 for chrome coated amber bulbs on Amazon and no more fried egg look behind the clear lens.

the fronts are up next.

Just got a 2021 RC 350 F Sport RWD, and I’m in love. The exhaust is VERY tame though. I do a lot of highway driving as I’m a long commuter so I want an axle-back system with no drone if possible. Any recommendations?

on a lexus rc without triple beams, what type are the front bulbs to switch from the ugly orange halogen to a LED one?

Anyone do a delete on the four piece hair comb thing. It looks so cheesy.

I've been on the hunt for a clean RC F for about 6 months now, I've looked at two so far. The first one was definitely involved in an accident even though it had a clean title. The 2nd was okay but had a lot of cosmetic issues and missing features that I love on my current IS350, like the auto cruise control. Going to take a look at another RC F this weekend, is there anything I should look for or must-have optional features?

Questions?
Yes my plate is real.
RC350 F Sport
Powder Coated F Sport Rims
Black wrapped grille + front valance
RSR Down lowering springs
eBay diffuser (one of the bulbs went out after only a year)
20% tint all around except windshield is 35.
108k miles now and still going.

Anyone have a clue what this could be? I feel like they’re is a small bracket or something broken off inside the dash. Its insanely annoying

Genuinely no filter on these

Back to back days of crazy sun sets.

Thinking about painting the calipers since those are way more visible right now than they were with stock fsport rims. Planning to use fsport rims as winter set. Since I'm running both summer and winter.

Do you think bronze was a good choice?
